Given numbers are 970, 162, 401, 815
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(970, 162) = 78570
GCD(970, 162) = ( 970 x 162 ) / 78570
= 970 / 162
= 970
Step2:
LCM(2, 401) = 802
GCD(2, 401) = ( 2 x 401 ) / 802
= 2 / 401
= 2
Step3:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
So, Greatest Common Divisor of 970, 162, 401, 815 is 1
